Firefly is presented in a durable milled aluminium chassis with rounded edges for comfortable in-hand use. The unit can be supplied with a rubber 'bumper' for added protection when being carried. Additionally the unit includes VESA mounting points on the rear of the case allowing mounting on monitor arms and stands if required.

Inside the chassis the Firefly includes:

A Dragonfly8 8-channel acquisition card with the standard feature set including signal conditioning mounting positions. This allows the Firefly to be upgraded with any of the Dragonfly range of signal conditioning modules.

A Pico-ITX Intel Dual Core Atom CPU card running Windows 7 or later. This allows the Firefly to run all current HGL software applications and additionally allows users to access any Windows based software such as Microsoft Office.

A 128 or 256 GB Solid State Disk (SSD) which allows 11 or 22 hours of continuous data storage at the maximum 80 kHz bandwidth on all 8 channels (44 or 88 hours of storage at 20 kHz bandwidth on all 8 channels).

A 4 Ah Lithium Ion battery which provides enough power to operate the Firefly for between 2 and 4 hours depending on operation. The battery is automatically charged when the 12 V external power is applied and can charge during operation when powered by the external 12 V supply.
